My name is Jeff Praissman with IBKR Podcasts, and it&#8217;s my pleasure to welcome back, for our monthly podcast, Market Chameleon&#8217;s Will McBride and Dmitry Pargamanik. Hey guys, how are you?&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-dmitry-pargamanik-nbsp\"><strong>Dmitry Pargamanik<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Hey, Jeff. How are you? Thanks for having us.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-jeff-praissman-nbsp-0\"><strong>Jeff Praissman<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Oh, my pleasure. We just wrapped up a great webinar on analyzing single-leg option trades, and I\u2019m excited you guys swung by the podcast studio. We\u2019re going to do\u2014I don\u2019t know if \u201cdeeper dive\u201d is the right word\u2014but I guess a <em>different<\/em> dive. I highly recommend anyone listening to this podcast check out the webinar as well.&nbsp;<\/p>\n\n\n\n<p>I think we might as well get started if you guys are ready.&nbsp;<\/p>\n\n\n\n<p>All right. So, I\u2019d like to start off with just some basics on breaking down trade volume. First of all, what can the percentage of calls versus puts traded that day or that week tell the trader?&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-dmitry-pargamanik-nbsp-0\"><strong>Dmitry Pargamanik<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Yeah. When we&#8217;re analyzing option volume and option trades, it&#8217;s a little bit different than just looking at stock volume because options have different contracts. So, when we look at the total volume, you want to break it down and see what&#8217;s going on there.&nbsp;<\/p>\n\n\n\n<p>When we talk about option contracts, there are calls and there are puts. Just breaking those down into percentages can let us know\u2014are traders and users of options using calls and puts evenly, say 50\/50, or do they have a preference for calls or puts? Is it mostly call options or mostly put options?&nbsp;<\/p>\n\n\n\n<p>That could point us to where that trading volume and order flow are heading. Sometimes, you\u2019ll get much more call volume than put volume, and that might even be normal for certain stocks. If you track the benchmarks and suddenly see something unusual happening\u2014like 90% of the volume in puts versus calls\u2014that might alert you to research it further because it\u2019s unusual. Even if the volume itself isn\u2019t out of the ordinary, the order flow and the way people are using options may have dramatically shifted. Tracking the percentages or proportions of calls versus puts can alert you to that.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-jeff-praissman-nbsp-1\"><strong>Jeff Praissman<\/strong>&nbsp;<\/h3>\n\n\n\n<p>And kind of along the same lines, does it matter if the option trades are buys or sells for analysis purposes?&nbsp;<\/p>\n\n\n\n<p><strong>Dmitry Pargamanik<\/strong>&nbsp;<\/p>\n\n\n\n<p>When we look at option order flow, of course, every trade has a buyer and a seller\u2014that\u2019s needed for a transaction. A lot of traders who study the order flow and the tape are trying to determine how is that order flow coming into the markets from end users?&nbsp;<\/p>\n\n\n\n<p>The assumption is that market makers are providing liquidity, so traders look at how the \u201ctakers\u201d are behaving. Are they coming in more aggressively from the buy side or the sell side? Where is the heavier volume order flow coming in? Are they buying premiums\u2014buying options\u2014or selling options?&nbsp;<\/p>\n\n\n\n<p>If you can model that out and determine how the order flow is coming in, that could impact how you strategize, place orders, and approach your trades. As a trader, the more information you have\u2014and if you know the markets better than everyone else\u2014it gives you a certain advantage.&nbsp;<\/p>\n\n\n\n<p>It\u2019s very common for traders to try to model that out and determine whether order flow is coming in mostly from the buy side or sell side.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-jeff-praissman-nbsp-2\"><strong>Jeff Praissman<\/strong>&nbsp;<\/h3>\n\n\n\n<p>One of the things I\u2019ve noticed when I\u2019m looking at option volume is, let\u2019s say someone trades a thousand contracts in a day, and there are four expirations\u2014it\u2019s generally not 250 contracts per expiration, evenly spread out. It tends to congregate around a few expirations.&nbsp;<\/p>\n\n\n\n<p>How can traders use these volume spikes in particular expirations or even specific strikes? How can they use that information to guide their analysis?&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-dmitry-pargamanik-nbsp-1\"><strong>Dmitry Pargamanik<\/strong>&nbsp;<\/h3>\n\n\n\n<p>That\u2019s a good point. When we look at trading volume, we can break it down into calls and puts, but options also have different expirations.&nbsp;<\/p>\n\n\n\n<p>You could have short-term, shorter-dated expirations, or longer-term expirations. You want to see how trading volume is distributed among those expirations. Is it evenly spread, or is there a preference for particular expirations? That can tell us a little about how people are using options and the type of risks they\u2019re targeting.&nbsp;<\/p>\n\n\n\n<p>Sometimes, volume is very heavy in shorter-dated expirations\u2014sometimes even 0DTEs (zero days to expiration). In certain products, 0DTE options are the busiest because people are using them for their outlook on that particular day\u2014whether that\u2019s direction or volatility. Other times, you\u2019ll see concentrated volume in longer-dated expirations.&nbsp;<\/p>\n\n\n\n<p>You might see an expiration that\u2019s two or three months out with unusually high volume. Why would people start looking at that? It could be tied to a particular event\u2014earnings, an announcement, or maybe a biotech stock awaiting FDA approval. Looking at expirations and volumes can give you insight into what traders are focusing on and what types of risks they\u2019re targeting.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-jeff-praissman-nbsp-3\"><strong>Jeff Praissman<\/strong>&nbsp;<\/h3>\n\n\n\n<p>And, as we all know, options are complex instruments. Unlike trading stocks, where Trader A buys a share of XYZ and Trader B sells a share of XYZ\u2014resulting in a net volume\u2014you can\u2019t look at option volume quite the same way.&nbsp;<\/p>\n\n\n\n<p>With stocks, you can simply say, \u201cx amount of shares traded per day,\u201d and leave it at that. But with options, as we\u2019ve discussed, there are different expirations and different strikes.&nbsp;<\/p>\n\n\n\n<p>So, it\u2019s obviously not the same thing if Trader A buys an at-the-money December call while Trader B sells an out-of-the-money February call. Those are very different trades, with very different Greek values and philosophies.&nbsp;<\/p>\n\n\n\n<p>What do you guys look for regarding the Greeks when analyzing single-leg option trades?&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-dmitry-pargamanik-nbsp-2\"><strong>Dmitry Pargamanik<\/strong>&nbsp;<\/h3>\n\n\n\n<p>That\u2019s a very good point. Trading 100 contracts of one option isn\u2019t the same as trading 100 contracts of a different strike or expiration. With stocks, 100 shares is always 100 shares\u2014but not with options.&nbsp;<\/p>\n\n\n\n<p>To convert the option volume into a risk metric, we use the Greeks. For example, we can convert the volume into its delta risk, gamma risk, vega risk, or theta risk. That can tell a different story.&nbsp;<\/p>\n\n\n\n<p>For example, is there a lot of directional risk in a particular option? Then it\u2019ll have a large delta. Out-of-the-money options, on the other hand, may have very low delta values, meaning they won\u2019t move much unless there\u2019s a significant move in the underlying stock.&nbsp;<\/p>\n\n\n\n<p>If you look at vega, which measures sensitivity to implied volatility, you\u2019ll find that longer-dated options have much higher vega risk. They\u2019re more sensitive to changes in implied volatility compared to short-term options.&nbsp;<\/p>\n\n\n\n<p>By converting option volume into their Greeks\u2014delta, gamma, vega\u2014you can paint a different picture of how traders are using options and what types of risks they\u2019re targeting in aggregate.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-jeff-praissman-nbsp-4\"><strong>Jeff Praissman<\/strong>&nbsp;<\/h3>\n\n\n\n<p>And could you dive a little further into delta analysis? You mentioned wings and tails earlier. Let\u2019s say you saw a huge amount of really out-of-the-money calls traded. No one\u2019s saying you\u2019re predicting the future, but what could that suggest a trader might be expecting?&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-dmitry-pargamanik-nbsp-3\"><strong>Dmitry Pargamanik<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Yeah. When we look at options, another way we can analyze volume is by breaking it into buckets based on deltas. Are traders targeting at-the-money deltas, out-of-the-money deltas, or in-the-money deltas?&nbsp;<\/p>\n\n\n\n<p>If we see an unusual concentration in out-of-the-money calls\u2014that\u2019s a wing or tail\u2014it doesn\u2019t typically happen. It could indicate something significant. You\u2019d ask, \u201cWhy is this happening? Who\u2019s doing it?\u201d It could reflect a change in sentiment or order flow.&nbsp;<\/p>\n\n\n\n<p>You\u2019d also look at skew to see if there\u2019s some reason\u2014like news or an event\u2014that\u2019s making traders believe there could be an unusual upside move. Monitoring that could give you new information about what the market is signaling.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-jeff-praissman-nbsp-5\"><strong>Jeff Praissman<\/strong>&nbsp;<\/h3>\n\n\n\n<p>And I actually want to take a second to tie in what we\u2019ve talked about so far and just point out to our listeners a trader could buy 50,000 deltas by selling puts or buy 50,000 deltas by buying calls, and the analysis would look very different, right? They\u2019re either buying the vol or selling the vol. So, it really seems like it\u2019s important to look at everything going into it. Just focusing on one piece doesn\u2019t really tell the full story for options, which, as we\u2019ve discussed, are fairly complex instruments.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-dmitry-pargamanik-nbsp-4\"><strong>Dmitry Pargamanik<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Exactly. What options were used to get that 50 delta, and how did they do it?&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-jeff-praissman-nbsp-6\"><strong>Jeff Praissman<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Right.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-dmitry-pargamanik-nbsp-5\"><strong>Dmitry Pargamanik<\/strong>&nbsp;<\/h3>\n\n\n\n<p>It\u2019s very important.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-jeff-praissman-nbsp-7\"><strong>Jeff Praissman<\/strong>&nbsp;<\/h3>\n\n\n\n<p>And one thing I was thinking about the other day\u2014there are currently 18 option exchanges in the U.S. Most options trade on almost all of them, if not all, right? I mean, there are still some single-listed options, but very few. For the majority\u2014especially the top 100 or 200 stocks\u2014I\u2019m sure they all trade on every exchange.&nbsp;<\/p>\n\n\n\n<p>Do you factor the exchange where the contract trades into your analysis? And if so, why? It\u2019s the same contract, right? So how can that help the trader?&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-dmitry-pargamanik-nbsp-6\"><strong>Dmitry Pargamanik<\/strong>&nbsp;<\/h3>\n\n\n\n<p>When we look at the options exchanges, it\u2019s very fragmented. You can trade on, like you said, 16 or 18 different exchanges at this point. One of the things you may want to look at is if we analyze the volume and trades, is that volume distributed evenly, or is there a concentration of volume on one or two exchanges?&nbsp;<\/p>\n\n\n\n<p>That can be important, especially if you\u2019re a trader trying to determine where you get the best price execution or where you\u2019re more likely to get an immediate fill. If you don\u2019t get an immediate fill, there\u2019s a bigger chance the stock moves away from you, and you miss your trade.&nbsp;<\/p>\n\n\n\n<p>So, if you\u2019re routing an order to a particular exchange, you may want to see where the volume and trading activity are concentrated. The more trading volume on an exchange, the higher the probability you\u2019ll get a better fill in between the markets, a faster fill, and better execution.&nbsp;<\/p>\n\n\n\n<p>When it comes to routing orders directly or assessing where to trade, tracking where the volume is concentrated can really benefit traders. Good quality execution translates into profits, fewer expenses, and minimizing losses.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-jeff-praissman-nbsp-8\"><strong>Jeff Praissman<\/strong>&nbsp;<\/h3>\n\n\n\n<p>I\u2019ll take a second just to plug the IBKR Smart Router, which takes option and stock orders, pings all the lit exchanges, and works to get the best economic outcome for the trader.&nbsp;<\/p>\n\n\n\n<p>And, Will and Dmitry, in some of our past podcasts and webinars, we\u2019ve discussed different types of traders\u2014small, retail, professional, institutional. Is trade source something you take a look at and analyze as well? What can that tell you about the volume?&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-dmitry-pargamanik-nbsp-7\"><strong>Dmitry Pargamanik<\/strong>&nbsp;<\/h3>\n\n\n\n<p>When we look at order flow and trades, there\u2019s limited information on the tape, but you can try to make inferences from what\u2019s available.&nbsp;<\/p>\n\n\n\n<p>For example, if you see contracts that look like a one-lot or two-lot with not much volume around them, you might bucket that off as small or retail trades. Then, if you see very large blocks or orders\u2014300, 400, 500 contracts\u2014that\u2019s different. That\u2019s not someone with $2,000, $3,000, or $5,000 in their account. It\u2019s more likely an institutional trader or someone with a much larger account.&nbsp;<\/p>\n\n\n\n<p>By bucketing trades into retail-sized or institutional-sized, you can compare and gain insights into what types of traders are participating and what they\u2019re doing. Why is there an increase in retail trades in a particular stock all of a sudden? It could be something on social media, a news event, or something mentioned on TV.&nbsp;<\/p>\n\n\n\n<p>Understanding where the volume is coming from and who\u2019s participating is important. Retail traders, for example, are often reacting to news that\u2019s already public, so they\u2019re not typically seen as the \u201cinformed\u201d traders. Institutional traders, on the other hand, might act differently.&nbsp;<\/p>\n\n\n\n<p>If you see a big trade\u2014say, someone just put up 1,000 contracts\u2014you might approach that research differently. Why did it happen? Where did it come from?&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-jeff-praissman-nbsp-9\"><strong>Jeff Praissman<\/strong>&nbsp;<\/h3>\n\n\n\n<p>And kind of going back to implied volatility, what can the relationship between the change in implied volatility from the previous day to the day you\u2019re analyzing tell a trader?&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-dmitry-pargamanik-nbsp-8\"><strong>Dmitry Pargamanik<\/strong>&nbsp;<\/h3>\n\n\n\n<p>We\u2019ve been talking a lot about volume and trading activity. When we look at options, though, you want to know how is the trading volume impacting the option value?&nbsp;<\/p>\n\n\n\n<p>Option value is dynamic. It can change because of decay, delta movements, or implied volatility changes\u2014even without trading volume.&nbsp;<\/p>\n\n\n\n<p>To figure out how volume impacts option value, you can compare the implied volatility from the previous day\u2019s close to the current implied volatility. That can give you an idea of whether trading volume is pushing the value of the option higher or lower.&nbsp;<\/p>\n\n\n\n<p>It\u2019s one way to look at volume and price action together and see how they\u2019re correlated.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-jeff-praissman-nbsp-10\"><strong>Jeff Praissman<\/strong>&nbsp;<\/h3>\n\n\n\n<p>And I want to leave off with one final question regarding opening and closing trades. Is there a way for traders to know, when analyzing, if a trade is opening or closing?&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-dmitry-pargamanik-nbsp-9\"><strong>Dmitry Pargamanik<\/strong>&nbsp;<\/h3>\n\n\n\n<p>I mean, that\u2019s not information you get directly from the OPRA feed. You don\u2019t see whether someone is opening or closing a trade\u2014that\u2019s not part of the trade data that\u2019s delivered.&nbsp;<\/p>\n\n\n\n<p>But in certain instances, you can make inferences. For example, if you see a big trade\u2014let\u2019s say 1,000 contracts\u2014and the open interest was zero that morning, you can infer that it\u2019s an opening trade because there\u2019s nothing to close out. Open interest updates once a day, so if it\u2019s zero, there\u2019s no existing position to close.&nbsp;<\/p>\n\n\n\n<p>If there\u2019s already a lot of open interest and you see heavy volume, you can\u2019t always tell if it\u2019s opening or closing. You\u2019d need to wait until the next day, when the open interest updates, to see the change. If open interest increases, that suggests more positions were opened in aggregate.&nbsp;<\/p>\n\n\n\n<p>But on the trade tape itself, you don\u2019t see whether one side is closing or opening.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-jeff-praissman-nbsp-11\"><strong>Jeff Praissman<\/strong>&nbsp;<\/h3>\n\n\n\n<p>Got it.
